Low-temperature-stable titanium chelates and method for their preparation

Abstract

Isopropoxyalkoxytitanium bis(acetylacetonate) compounds are prepared by admixing diisopropoxytitanium bis(acetylacetonate) with a dialkoxytitanium bis(acetylacetonate), and allowing the mixture to react, optionally at elevated temperatures.

We claim: 
     
       1. The method of preparing a compound of the formula ##STR3## wherein X is ##STR4## and R is ethyl, n-propyl, n-butyl, isobutyl or tert.-butyl, which comprises admixing a compound of the formula (isopropoxy) 2  TiX 2  with a compound of the formula (RO) 2  TiX 2 , wherein R and X have the meanings defined above, in a molar ratio of 1:1 in the liquid phase, and allowing the mixture to react at a temperature between 20° and 100° C. above the melting point of the higher-melting-point reactant for 0 to 60 minutes. 
     
     
       2. The method of claim 1, wherein the mixture is allowed to react thermally at a temperature between 1° to 30° C. above the melting point of the higher-melting-point reactant for 30 minutes. 
     
     
       3. The method of claim 1, wherein the said compounds are admixed in molar ratios of 1:0.1 to 1:1.9.
